Great kit! Heavy gauge steel brackets. Will terst the arms on the track to see how well it's going to hold up. The only downside id that there is no front bracket for the arms in this kit. I am assuming its for a z'ed frame where you would bolt the arms directly to the frame.
This kit is for use with Speedway Model A frame 916-57045 which has the required front brackets pre-welded to the frame.

This four bar kit is meant to be ordered as an add on to our Speedway frame number 91657045. It should allow for sufficient pinion angle of 2-4 degrees. In setting pinion angle remember the chassis needs to be at ride height with the four bar links parallel to the ground. If hanging on jack stands you will be unable to set the appropriate pinion angle. Ride height is the term referring to the vehicle stance ready to go with all the weight on the vehicle.
